UNITED STATES PATENT OFFIon.

WASHINGTON FOGLESONG, OF DAYTON, OHIO, ASSIGNOR TO THE DRIPPING PANCOMPANY, OF SAME PLACE.

IMPROVEMEN T IN WlRE-BENDING MACHINES.

Specification forming part of Letters Patent No. 185,514, dated December19, 1876 application filed July 24, 1876.

Be it known that I, WASHINGTON FOGLE- SONG, of Dayton, Montgomerycounty, State of Ohio, have invented an Improvement in Machines forBending Wire, of which the following is a specification:

My invention has for its object, principally, the bendingof wire intoregular shapes, rapidly and conveniently, for the wiring of sheetmetalpans; and it consists, in the first part, in the combination of arotating spindle, carrying the form, with a pressure-arm to press theWire to the form as the latter revolves. Myinvention consists, in thesecond part, in connection with the rotating form, of a series ofguides, set spirally upon the form, to give the proper guidance to thewire in the formation of the first turn. My invention consists, in thethird part, in a certain combination of devices, by which the form maybe increased "or diminished in size, to make wires for different sizesofpans.

Figure 1 is a side elevation of a machine embodying my invention. Fig. 2is aperspective view of the pressure-lever. Fig. 3 is a perspective viewof the form.

A is the main frame of the machine, having ordinary beariligs, in whichthe shaft B is journaled, which may be driven by gearing or pulley, or,for small wire, turned by a crank. To the shaft B a head, 0, is firmlysecured, to which two heads, D D, are fitted to slide, the latter beingadjusted to and from each other by separate screws 01 d.

Upon each of the sliding heads D D two other slides, E E F F, are fittedto move, being adjusted to and from each other by separate screws 6 eff.

To the four slides E E F F four posts, G, are firmly secured, and theouter surfaces of these posts constitute the form proper, upon which thewire isshaped, and they gepresent exteriorly the configuration of thepan or other article for which the bent wire is intended. Being attachedto the slides E E F F, the posts are expansible, sothat the form may beincreased or diminished from one size square to another, or changed froma square to a rectangle.

By the use of a different number of posts the wire may be bent intriangular form, and by the use of non-expansible forms ellipses andlike figures may be formed, the important active agent, in connectionwith the revolving form, being the reciprocating pressure-bar H, whosemotion, following as it does the configuration of the form, causes, byits pressure, the wire H to hug the form and adopt its shape.

It is proposed to wrap the wire in spiral shape, and to make as manywrappings as the posts G will contain, so that wires sufiicient forquite a number of pans or vessels may be made at a single operation ofthe machine, the coil of wire, after being bent, being cut at one of thecorners or sides.

To support the posts rigidly, I introduce gage-plates I, one or more,and these may be marked for standard-size pans, so that they may be usedto set the posts up to, in efiecting' their proper adjustment.

To guide the wire in eii'ecting the first turn, I fix guiding-steps K tothe bases of the posts, which serve to push out the wire and lever H tothe extent of one-fourth the thickness of the wire at each corner, andthus enable the wire to lap and pass the first end of the wire aftermaking one turn, the first end being bent down and inserted in apertureg before the bending commenced.

The wire in the process of bending lies in in the rabbet h of the bar H,and as the bending proceeds the wire in being wrapped spirally graduallypushes out the lever laterally, the latter being fitted to swing looselyand move sidewise on the shaft or rod L.

Guides M M are attached to the under side of the lever H, one of which,M, provides for vertical play, and the other confines it strictly to thepath of the rabbet in every direction. The pressure of the lever may beregulated by the weight of the lever itself, or the addition of aweight, N, or by any other well-known expedient adapted to this end. Thewire, before passing to the bending appliances, may be straightenedcontinuously by the hollow rotary straightening-mandrel I, used commonlyfor this purpose.

I claim- 1. In a machine for bending wire, the combination of a rotaryform or pattern, and areciprocating pressure-bar acting upon the wirepattern by pressing it directly against the same, substantially asdescribed.

2. In combination with the form G, the

series of ledges or guiding-steps K, substantially as and for thepurpose specified.

3. In combination with the form-posts G, the sliding adjustable plates EE F F, and

sliding adjustableheads b a set my hand. WAS summon noennson'e.
